SPECIFICATION forming partei Letters Patent No. 560,818, dated May 26,1896.

Application iiled March 26, 1895. Renewed November 4, 1895. Serial No.567,957. (No model.)

To all whom t 11mg concern: Be it known that I, WILLIAM J. RANTON, ofvSyracuse, in the county of Onondaga, Ain the State of New York, haveinvented new and useful Improvements in Generators, of which thefollowing, taken in connection with the accompanying drawings, is afull, clear, and exact description. y

This invention relates to improvements in generators, `particularlyapplicable for heating houses and other buildings, and has for itsobject the production of a simple and practical device which is highlyeflicient in operation and durable in use; and to this end it consists,essentially, in the general construction and arrangement of the parts ofthe generator, all as hereinafter more particularly described, andpointed out in the claims.

In describing this invention reference is had to the accompanyingdrawings, forming a part of this specification, in which like lettersindicate corresponding parts in all the views.

Figure lis a front elevation of my improved generator. Fig. 2 isavertical section taken on line 2 2, Fig. l; Fig. 3 is a transversesec-- tion taken on line 3 3, Fig. 2; and Figs. 4L and 5 are transversesections taken, respectively, on lines 4E 4 and 5 5, Fig. 2.

A and B represent, respectively, the inner and outer shells of myimproved generator, which, as best seen at Fig. 1, are formed ofsubstantially the same length. The inner shell A preferably tapers fromits base toward its upper end and is usually formed circular incross-section. rIhe outer shell B is preferably formed with uprightwalls and is also usually formed circular and provided with manholes b,closed by caps b and suitable fastening means b. The ash and combustionchambers O O of theV generator are preferably inclosed `by the lower endof the shell A, which extends upwardly above the combustion-chamber. Asuitable grate c is arranged within the lower end oi the shell A and ismounted upon any desirable construction of support c'. A fuel-inletpassage O2 and an ash-door a are arranged above and below the grate cand the assa'e C2 isclosed b a door a. The Jasy sage C2 is preferablyformed by a shell c2, havingi ts opposite ends provided withoutwardlyprojecting flanges secured by suitable fastening means o3 tothe adjacent faces of the shells A B. Said grate and fuel-inlet passageform no part of my present invention, and consequently they may be ofany desirable form, size, and construction.

A water-containing chamber D is formed between the shells A B, and topand bottom plates E F interposed between the opposite ends of the shellsA B. The plates E F are formed with downturned flanges c f, arrangedwithin the adjacent ends of the shell B and at the outside `of thecorresponding ends of the shell A, and these iianges are secured inposition by suitable fastening means e f. Any desirable construction ofwater-glass D and pressure-indicator D2 may be connected to the chamberD; but as `said parts form no part of my present invention it isunnecessary tofurther illustrate and describe the same. The peculiarform of the shell A compels the products of combustion to impingedirectly against its inner face, but does not prevent combustion of thegases or unduly retard the same. The Water is also arranged in acomparatively thin body or sheet entirely surrounding the inner shell A,and is consequently easily heated. The utilization of the heat of theproducts of combustion is also greatly facilitated by flues presentlydescribed and water-tubes a2 c3, which are arranged one .above the otherand extend transversely across the shell A. The outer ends of the tubesa2 as are secured to the shell A, and a similar transverse tube a4 isarranged midway between the tubes (t2 a3 and at right angles thereto.

G II are inner and outer upper draft-chambers arranged above the topplate E, and I is a lower draft-chamber arranged beneath the bottomplate F between the lower ends of the shells A B. The draft-chamber Gdecreases in area toward its top and is formed with an upwardly-crowningtop wall g, extending upwardly from the top plate E and provided with anoutwardly-projectin g flange g", se-

cured to said plate E. The upper portion of the wall gis formed with anaperture g2, which is opened and closed by a damper g3. The chamber IIis formed with an upwardly-tapering top wall h, extending from the topplate E and formed with a projecting flange 7L', se-

cured to said plate E. The upper end of the wall 7L is provided with anoutlet-opening h2, to which a suitable draft-pipe (not illustrated) maybe connected, and said wall is formed with a series of doors Il. Ahand-piece g4 is guided through the wall h of the chamber II and isconnected to the damper g3, which is movable in guides g5, secured tothe inner face of the wall g beneath the aperture g2.

.DoWnflow-flnes J, inclining toward each other from their lower ends,connect the chambers G I, and substantially upright upflowflues K,interposed between the iiues J and the shellB, connect the chambers III. The products of combustion, after impinging against the inner face ofthe shell A and the outer faces of the tubes a2 as a4, enter the chamberG and then either pass from the chamber Gr directly through the apertureg2 and the opening h2 or else through the ilues J, chamber I, and fluesK to the chamber II and thence through the opening h2.

Additional flues M connect the fuel-inlet passage C2 with thedraft-chamber II for additionally heating the overlying water, and theseflues M also operate to increase the direct draft from thecombustion-chamber and to prevent the escape of gas when fuel is beinginserted. The described construction of fines is particularly practicaland effective and serves to reduce to a minimum the amount of fuelrequisite for operating my improved generator.

The operation of my invention will be readily perceived upon referenceto the foregoing description and the accompanying drawings, and it willbe particularly understood that it consists of but few parts, which areeasily manufactured and assembled, insures conibustion of the gases in achamber of comparatively large diameter and the effective utilization ofthe heat of said gases.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

l. In a generator, the combination of an inner shell inclosing thecombustion-chamber and extending upwardly therefrom, an outerwater-containing shell surrounding the inner shell, top and bottomplates between the opposite ends of the shells, separate inner and outerupper draft-chambers above the top plate, a damper for closing the innerupper draftchamber, va lower draftchamber beneath the bottom plate, andinclined downflow and upright upflow flues respectively connecting theinner and outer upper draftchambers with the single lower draft-chamber,substantially as and for the purpose specified.
